Specification of Letters Patent.

Application filed February 3, 1913. Serial No. 745,874.

To all whom it may concern:

Be it known that I, FRANK H. Bronson MANN, a citizen of the United States, residing at Nor-wood, in the county of Hamilton and State of Ohio, new and useful Improvements in Flexible Metallic Protectors for Rubber Tires, of which the following is a specification.

My invention relates to simple, efficient and economical means for covering and protecting rubber tires.

The object of my invention is to provide a sectional, flexible metallic covering for rubber tires which will prevent any dam-' age to the same in use.

A further object is to insure a tire protector which will lengthen the life of the tire by preventing puncture by nails, glass and otherwise, to prevent tires from expanding sufficiently to blow up, to arrest the rapid wearing of treads or casings of tires and to prevent tires from being forced off of wheels by high rate of speed or heavy side pressure as in case of skidding.

y invention consists in a device that is described or suggested in the following dedrawings and any modifications thereof which are covered by. the claims.

Referring to drawings: Figure 1 is a side view of the protector, part of segments in section and part of ring broken awayfor clearness in describing my invention. Fig. 2 is a sectional detail of casing on line a-a, of Fig. 1; Fig. 3 is a perspective view of one of the segments. Fig. 4 is a sectional detail showing protector at rest. Fig. 5 is a similar sectional view as Fig. 4, but showing protector subjected to a downward force. Fig. 6 is a sectional detail view showing protector subjected to a side force.

In the drawings, and as illustrated, 1 indicates a segment and its contiguous segments, 2 a tread member of segment, 3 a neck or depressed member of segment allowing the tread member 2 of its contiguous segment 1, to overlap said member.

4 is a roller and 5 a pin carrying said roller and fastened to lug 6 of neck member 3, roller 4 engaging in slot 7 located on lug 8 of tread member 2. Slot 7 has a lateral clearance for roller 4, allowing circumferential movement of segments.

have invented certain,

9 represents the clearance between the segments provided by slot 7 in segments.

10 is a ring fastened to felly 11 by means of bolts 12. Slots 13 in ring 10 have a radial clearance and engage roller 4.

As the weight of the vehicle is carried by thewheels and the tires being resilient, the resultant lines of force will be upward and outward.

From the description thus far explained it will be readily understood that the protector consists of a plurality of segments having a circumferential and radial flexibility conforming with the tire when in action.

Proceeding with the description, 14 is a .reflexed edge on segment 1,- and 15 a reflexed edge on ring 10 interlocking with edge 14. Assuming the wheel to be raised from contact with the road and the tire inflated, it will be seen that undue expansion of the tire will be arrested by means ofsaid refiexed edges, thereby preventing the blowing out of tires and in case of vehicles skidding the forcing off of the tire will be arrested by the above mentioned edgesl I provide an anti-skidding and noise lessening device by means of rubber buttons conveniently located on tread of protector.

16 is a rubber button cast over washer 17 and fastened to segments by means of screws 18, inserted through holes provided in tread member 2 of segments,

It may readily be seen that the renewal of buttons when worn out can be accomplished in a very short space of time andwith little expense, also that the neck member 3 of segments will prevent the screw 18 of button 16,

- being forced into casing of tire, thereby inj uring the same.

y invention provides for a. protector,

each formed of a treadoverlapping the neck member of its c0ntiguous segment, means to secure said overlap ping segments together comprising a slot disposed circumferentially of the wheel on the tread member of one segment, a pin on the neck member of the cooperating seg ment mounted in said slot, side plates, re-

. flexed edges on said side plates engaging the reflexed edges of the tread members and radial slots in said side plates to receive said 'pins, substantially as setforth and for the purposes specified.

2. In a tire protector, the combination of a cover comprising a series of cooperating segments each formed of a tread member and integral neck member, the tread member of one segment overlapping the neck member of its contiguous segment, the tread FRANK H. BRUEGGEMANN.
